Nexo pairs a native Rust launcher with a Fabric anti-doxxing mod — coordinate scrambling, pattern masking, and peer-to-peer LAN, without giving up an ounce of performance.
Every module below ships and runs today — alpha means rough edges, not vaporware.
Randomizes the coordinate readout shown by the F3 debug overlay before it ever hits a screen-share or clip, so a stray recording can't leak your base location.
Normalizes rotation metadata on placed blocks like signs, stairs, and logs, closing the classic trick of back-calculating coordinates from orientation angles in screenshots.
Masks the bedrock generation pattern at world bottom, which can otherwise be used to fingerprint your seed and border offset and triangulate a real-world position.
On servers with more than 50 players, the first F3 press with coordinates unobscured shows a warning instead of the debug screen — press again within ten seconds to open it anyway.
Your LAN world becomes reachable over the internet through an encrypted QUIC relay — no port forwarding, no router config, no exposed IP.
One link, one click. Friends are standing in your world in under two seconds, no account linking required on their end.
If the relay drops mid-session, the tunnel re-establishes itself in the background — nobody has to re-share a link.
Flood-fills through everything that isn't bedrock to find gaps sealed inside the Overworld floor and Nether roof, then outlines each one through the terrain as a single colour-cycling shape. No seed required, so it catches holes other players broke too.
Shows the world or server you're actually in, not just "playing Minecraft". Multiplayer activities carry a join secret, so friends running Nexo get a working Join button.
Glowing rounded buttons, animated starfield or Matrix-rain backdrops, and a modern bundled font — applied to other mods' menu screens too, and revertible to stock vanilla per component.
Bind chat commands to keys with send-all, cycle, random, repeat-while-held, and type-without-sending modes, plus placeholders for your name, position, and clipboard.
3D skin preview and rendering run straight on the GPU through wgpu — not emulated inside a bundled webview.
A compiled Rust binary, not a bundled Chromium runtime. The launcher opens before you've let go of the mouse.
Multiple Microsoft accounts, AES-256-GCM at rest, instant switching with no repeated sign-in.
A straight comparison against the other launchers people actually switch between.

The launcher runs on its own. The mod runs in any Fabric instance — Nexo's or the one you already have.
Installs per user, so Windows never asks for admin rights. Start-menu entry included, and it updates itself from then on.
Download for WindowsThe same launcher as a single file. Nothing is written outside its own data folder, so it runs from a stick.
Download portableOne executable, no runtime to install. chmod +x and run it — or take the AUR package if you're on Arch.
Every build is listed with its SHA-256 in SHA256SUMS.
Two builds from one source tree. Pick the second if you play somewhere that reviews what you have installed.
Every feature, including the ones some servers count as an advantage.
